Honestly though at what point does a subway just become to long though? We can't operate express service and does Union really have the capacity to be a terminus point for 2 lines assuming you split Line 1? There is definitely a point of diminishing returns were the Subway actually becomes its own worst enemy and you would be better off just building a higher order of transit (a GO Line).

The line is 57.1 km long. The entire TTC Subway is 76.9km. Line 1 is 38.8km long. I'd say we have a lot longer to go.
An extension to Wonderland would be about 6km. An extension to RHC would be 7km. So, 38.8+6+7=51.8km Still 5.3km short of the longest line.
In that time frame, Smart track and 15 minute all day GO wll be running. And most likely DRL and possibly DRL long will be built. I'd say that the area is doing everything short of truncating the line at Union.
